To all whom it may concern." I

Be it known that I, CARL L. TUCKER a citizen of the United States of America, residing at the city and county of Denver and State of Colorado, have invented a new 7 and useful Automatically-Operated Laundered-ShirtWVrapping-Envelope-M a k i n g' Machine, of which the following is a specification. I

My invention relates to a new automatically operating, laundered-shirt wrapping, envelope making machine. I. 3

And the objects of my invention are: First: To provide an envelope making machine that makes envelopes that are especially adapted to envelop and wrap and enclose laundered shirts, collars,'cuffs, handkerchiefs and other articles.

Second: To provide an envelope making machine that will make envelopes that have straight parallel sides of even width throughout their length, and that have a straight shirt receiving space or pocket throughout the length of the'shirt covering envelope, and that is provided with a lawn dered article entering aperture along one of itsfend edges.

Third: To provide a simple, practically operating envelope making machine that willautomatically make a very large number of envelopes each working day.

I attain these objects by the mechanism illustrated. in the accompanying drawings,

for folding the paper around the side edges of the card board, the supporting plate and card board being shown in section.

Referring to the drawings:

Figure 1 represents a side elevation, in section, of a laundered-shirt wrapping envelope making machine embodying my invention. I

In this side sectional elevation, the numeral 1 designates a supporting frame, which consists of vertical legs or posts 2 and 3, which support horizontal side bars 4, which are connected by end cross pieces 5.

The vertical posts 3 and their connecting cross piece 5 represent the front end of the machine, and the posts 3 exte d above the horizontal side bars 4 a short istance, and

on their outside faces I secure a pair of.

alined shaft supporting boxes 6 at their up- I per' ends above the side bars 4, and a pair of shaft supporting boxes 7 below the side bars 4. I

A shaft 8 is journaled in the boxes 6, and a shaft!) is journaled in the boxes 7. On the shaft 8, a roll 10 of thin wrapping paper is mounted, andon the shaft 9 a roll of thin card board 11 is mounted.

The roll of cardboard is in the form of a strip that is about nine inches wide, and the roll of paper is about twelve inches wide, and both the card board and the paper are out and connected together to form an er.-

velope that has parallel sides and edges of even width throughout its. entire length, and

my machine makes envelopes having two different lengths of thin paper; hut it pref erably uses an envelope having a card board whose length is generally about sevent/een inches for laundered bosom shirts, while the thin paper would be preferably about fourteen inches long for the shortest'size My invention contemplates. however, the mak- I ing of envelopes of different lengths, but

with parallel side edges and parallel opposite sides that form the straight envelope space between the card board and the thin paper, into which the shirt is placed, and that is of even width throughout the length of the envelope, and to provide envelopes that have the card board back portion made about three inches longer than the length of the thin paper that covers the shirt.

The paper is made enough wider than the card board to allow plenty of room between it and the card board to insert a shirt and a few collars and handkerchiefs between it and said card board, which is accomplished by laying the lower end of the shirt on the projecting end of the card board and raising the edge of the paper up enough to insert the lower end of the shirt under it and then push the shirt along the card board and between it and the card board, to the lower end of the envelope, and in order to accomplish this, the sides ofthe paper are pasted in a straight line along the underside of the back of the card board, and at an equal distance from the edges of the card board along its entire length; consequently, when the paper is pasted to the underside of the card board, its opposite edges are folded over and underneath the edges of the card board, byspecial folding mechanism which will be presently described, and about an inch of its opposite edges are pasted to the opposite side of the card board, along and parallel to the edges of the card board, and while this is being done, the paper lies flat against the top or upper side of the card board and projects over its opposite side edges. Consequently, when the envelope is first made, there is a surplus of the paper along its opposite side edges that projects over the opposite edges of the card board far enough to allow the said paper to be raised up far enough above the card board to easily insert a shirt and a few collars and handkerchiefs between it and the card board. 7 I

\Vhen making envelopes in which the card board and paper are the same length, or seventeen inches long, I employ two pairs of rollers, one pair being adapted to receive the paper and card board and feed the same forward, the other pair being arranged to receive the card board and paper from the first pair, and cut or sever the card board and paper once in each complete revolution of. the said rolls, and as these rolls are seventeen inches in circumference, the material passing between them is cut into strips which are seventeen inches in length.

I will now describe the mechanism employed for cutting the materials into equal a third of their lengths from their front ends are bolted pillow blocks 12, and on the under sides of said bars, and directly beheath the pillow blocks 12, are bolted pillow blocks 13, the two pillow blocks on each side bar being clamped to the side bar by the same bolts 14, which extend through the base portions of .the pillow blocks and through the side bars. Bearing boxes are supported in the blocks 12, between coil springs 16 and 17. The springs 17 rest upon the side bars 4; and caps 18 are inter-posed between the upper ends of the springs 16 and the upperends of the blocks 12, and screws 19 pass through threaded holes in the upper ends of the blocks 12 and are screwed against the caps 18, for a purpose to be presently described.

Bearing boxes 20 are supported in the blocks 13 upon coil springs 21, a cap 23 being interposed between the lower ends of the springs 21 and the lower ends of the blocks 13, and screws 24 pass through threaded holes in the lower ends of the blocks 13 and are screwed against the caps 23. Screws 25 pass through opposite sides of the block 12 and bear against opposite sides of the boxes 15, and screws 26 pass through the opposite sides of the blocks 13 and bear against opposite sides of the boxes 20. A shaft 27 is supported in the boxes 15, and a shaft 28 is supported in the boxes 20, and on these shaftsjare rigidly mounted metal rolls 29 and 30, respectively, which are of a length corresponding to the width of the roll 10 of paper, and preferably seventeen inches in circumference. The upper roll 29 has a narrow flange 31 at each end,.which overlaps the adjacent end of the lower roll 30, and these flanges are adapted to guide the paper as it passes in between the rolls 29 and 30. By adjusting the screws 25 and 26, the rolls 29 and can be accurately alined with respect to each other, and by adjusting the screws 19 and 24 the rolls may not only be arranged in true parallel relation, but may also be properly spaced for the purpose required. The coil springs which bear against the boxes 15 and20 provide a resilient support for the said holes, which therefore permit a yielding movement of the rolls 29 and 30 with respect to each other. The rolls 29 and 30 will hereafter be termed the feeding rolls..

The paper strip 10 and the card board strip 11 are passed between these two rolls, and the said rolls are adjusted toclamp the said paper and card board with sufficient pressure to feed them continuously forward. At each end of the roll 29, and in the face thereof are formed short recesses or slots .1 in which are secured in any suitablemanner, knives 2 which project a very slight distance beyond the face of the roll. The end portions of the roll 30 are also provided with short recesses or slots 3' in which are secured in any suitable manner, hard wood blocks 4 which are adapted to register with the knive's2 on each complete rotation of the rolls, and thus receive the cutting pressure of the said knives.

These knives are adapted to cut slits about one inch long in the opposite edge portions of the paper, at each rotation of the rolls, the slits acting to facilitate the folding. of the paper around and under the side'edges of the card board, as will be hereinafter fully set forth. a

.A suitable distance beyond the pillow blocks 12 and. 13, pillow blocks 31 and 32,

' 31. and 32 are provided with box alining screws 38 and 39 respectively, and screws 40 and 41 respectively for effecting vertical adjustment of the boxes.-

In the boxes 31 and 32, are mounted shafts 42 and .43, respectively, on which are rigidly secured metal rolls 44 and 45, respectively,

which are of the same length and circumference as the rolls 29 and 30. The upper roll 44 has a narrow annular raised portion 46 at each end thereof, of slightly greater diameter than the remainder of the roll, and

when the said'raised portions 46 bear upon the lower roll 45, they define a slight space between the lower roll, and that portion of the upper roll lying between the said raised portions 46, the purpose of which will hereinafter appear.

The rolls 44 and will hereafter be termed the cutting rolls.

The upper roll 44 is formed with a longitudinal groove 47-see Figures 5 and 8- which extends the full distance between the raised portions 46 and one side of the groove is inclined, while the opposite side thereof is at right angles to the bottom of the groove. A knife 48 lies against the latter side, and projects beyond the groove a distanceequal to the depth of the raised portions 46, or in other words, the cutting edge of the-knife is flush with the faces of the said raised portions. A clamping strip 49 is placed against the knife, its inner edge being inclined or beveled at an opposite angle to the inclined edge of the groove 47, and a' wedge strip 50, having beveled side edges, is placed in the groove and bears against the bevel edge of the groove and the beveled edge of the clamping strip 49, as clearly shown in Figure 8, and screws are passed through the wedge strap 50 and screwed into the wall of the roll, thereby jamming the clamping strip 49 against the knife, which is thus clamped against the side of the groove 47 and securely held against accidental displacement.

The roll 45 is formed with a longitudinal groove 51v in which is placed a metal bucking strip 52 which is flush with the surface of the roll and which is adapted to register with the knife at each complete rotation of the rolls 44 and 45 and receive the cutting pressure of the knife as it severs the paper and card board, as will hereinafter be more fully set forth. The shaft 27 has. keyed thereon a gear wheel 53, which meshes with a gear wheel 54 of the same diameter, on

the shaft 28, and the shaft 42 has keyed thereon a gear wheel 55 which meshes with a gear wheel 56 of the same diameter, on the shaft 43. See Figure 5.

The shaft 43 also has a sprocket wheel 57 rigidly secured thereon, which is connected by achain 58, with a sprocket wheel 59 on the shaft 28. The shaft 42 has a belt wheel 60 on one end thereof, which is adapted to be connected by a belt with a powerdriven pulleynot shown. Thus, when the shaft 42 is driven, its gear wheel 55, meshing with the gear wheel 56, turns the shaft 43,. and the chain and sprocket connection between the shafts 43 and 28, effects the rotation of the latter shaft whose gear 54, meshing with the gear 53 on the shaft 27, causes the latter shaft to rotate, and thus the feeding rolls 29 and 30, and the cutting rolls 44 and 45 all rotate in unison, and so as to feed the paper and card board continuously forward.

The shaft 42 has rigidly mounted thereon two relatively thickdisks 1 which abut against the ends of the hubs of the roll 44, and these disks are provided with annular grooves 2 The shaft 43 is provided with similar disks 3*, having annular grooves 4 A metal frame 5 having straightsides and semi-circular ends, loosely surrounds each pair of grooved disks 1 and 3 and set screws 6 pass through threaded holes in the ends of the frames 5 and enter'the grooves in the disks, and are adapted to be screwed against the bottoms of said grooves thereby to prevent spreading of the rolls 44 and 45 .under the pressure imposed by the cutting action of the knife 48. By adjusting the set screws 64, the rolls 44 and 45, will automatically adjust themselves to card boards of varying thicknesses, thus assuring the proper feeding of the card board and paper he tween'the said rolls.

A sheet metaltable orbed plate 61 is positioned between'the feeding rolls and the cutting rolls, and is bolted at its ends to the under sides of the side bars 4, as clearly shown in Figure 1. A rectangular opening is formed in the bed plate, adiacent to the feeding rolls, and a correspondingly shaped glue pot 62, having a flanged rim 63, is placed in the said opening, its flange 63 resting upon the marginal edges of the said opening. A shaft 64 is supported in the ends of the said glue pot and has secured thereon two disks 65, which are spaced apart a distance slightly less than the width of the card board 11.. These disks are of the same diameter as the rolls and are preferably about three eighths of an inch thick, and their highest points are slightly above the level of the rim of the glue pot. These disks are adapted to supply parallel lines ofliq-uid glue to the under side of the card board, adjoining the side edges thereof, as the card board passes over them from the feed rolls to the cutting rolls, as will hereinafter fully appear.

Upon the bed plate 61, between the glue pot and the cuttin rolls, is secured a table 66, in the form of a flat horizontal metal plate, the side edge portions of which are bent down at right angles and then outward to form supporting strips 67, which are screwed to the bed plate. The face of the table 66 is on a level with the meeting points of'the rolls 4% and 4-5, and it is about one inch narrower than the card board 11, so that when the card board passes over it, the said card board will extend one-half inch beyond each side of the table, and it is these projecting portions of the card board which are striped with glue on their under sides, as they pass over the disks 65.

The cardboard and paper together are moved over the table, the paper being on top of the card board, and before passing between the cutting rolls, the paper must be folded around and under the side edges of the card board,so that the edgeportions of the folds will be pressed against the lines of glue on the card board, by the said rolls,

and the folding operation is accomplished in the following manner:

On each side of the table 66 are arranged fol dingdevices 68 in the form of sheet metal strips, which are bent to form angle plates,

the vertical wings of which converge toward their rear ends, or the ends adjacent to Cal the cutting rolls. These folders lie in openings 69, formed in the bed plate and are supported by angle strips 70, which are secured to the horizontal wings of the folders, and

are screwed to the bed plate, as ,clearly shown in' Figure 1. i The horizontal wings of the folders lie slightly above the plane of the 1 table 66, and theirvertical wings gradually merge into horizontal portions 71, near their rear ends, so that the rear ends of the folders gre V-shaped, as clearly shown in Figure x The front ends of the vertical wings of the folders are slightly farther apart than the width of the paper 10, and the rear ends of the said folders are about an inch further apart than the width of the card board 11;

or in other words, the vertical wings of the folders converge from a distance apart of about twelve inches at their forward ends to a distance apart of about ten inches at their rear ends. To the sides of the table 66, are secured horizontal plates 72, which extend laterally beneath thehorizontal wings of the folders 68, and the outer edges of the plates converge at the same angle as the vertical wings of the said folders, a slight space be ing left all around between the folders and the plate 7 2.

The plates 72 and the folders 68 are the same length, and each plate is given a slight upward and outward bend along a line onehalf an inch from the side of the table, and this one-half inch of the width of the plate next to the table is on a slightly lower plane than the table, while the remainder of the plate is on the same plane as the table, as clearly shown in Figure 6. The object of having that part of the plate adjoining the table on a lower plane than the table, is that it may not come in contact with the under side of the extended edge portion of the card board, which has a strip of glue on it, as previously described.

The plates 72 act in conjunction with the folders to curl or turn the side edge portions of the paper over and under as the paper and card board are carried forward to the cutting rolls. The paper, as it passes under the horizontal wings of the folders, engages the converging vertical wings of the said folders, and is first gradually turned down at right angles over the edges of the plates 72, and then, as it reaches the point where the vertical wings begin to merge into horizontal members, the paper is curled by the converging wings of the folders, around the converging edges of the plates and under them, as shown in Figure 6, so that the fold, at the advance end of the paper, extends onehalf inch beyond each side of the card board, and one-half an inch under the card board, but separated from the said card board by the plates 72. Then, as the paper and card board pass off the table and in between the cutting rolls, the folded edges of the paper are pressed against the under side of the card board, and held thereto by the glue.

The knives 2 cut slits X, one inch lon inthe opposite sides of the paper, and t ese slits occur where the paper passes from convergent edges of the plates 72, to the parallel edges of the card board, as shown in Figure 10, and they permit the folded converging edges of the paper to straighten out, without crumpling the paper at these points, so that the said edges will be parallel.

The roll 29 is provided with three shallow annular grooves 7 3 in which are placed three endless belts 74, and these belts pass around a roller 7 5, adjacent to the cutting roll 44;

tributing rolls 65.

the roller 75 being grooved to receive the belts, which are of a thickness corresponding to the depth of the grooves in the rolls 29 and 7 5. The roller 75 has trunnions 76 which are mounted in suitable bearing boxes 77, which are bolted to the bed plate. The space between the outer edges of the two outer belts 74, is the same as the width of the table 66, and these belts are adapted to press the paper against the card board as the paper and card board pass from the feeding to the cutting rolls, and also to press'the card board into contact with the glue dis- The belts 7 5 are held under the required tension by a roller 78, which rests on the upper laps of the belts, and is mounted in bearmg boxes 7 which are bolted to the flanged rim 63 of the glue pot. The tension is reg-ulated by screws 80, which pass through threaded holes in caps 81, of the bearing boxes, and bear against blocks 82, which rest on the trunnions of the said roller 78.

The machine thus far described is for the production of envelopes in which the card board and paper are of the same length, and the operation of the machine is as follows:

The card board and paper from their respective rolls, are inserted between the feed rolls 29 and 30, the paper being on top of the card board, and are carried forward by the rolls and the belts 74, over the glue distributing disks, which deposit a continuous line or stripe of glue to the under side of the side edges of the card board. The forward end of the table 63 extends over the glue pot a short distance, as shown in Figure4, and receives'the card board and paper from the glue distributing disks. The card board ex- ,tends one-half inch beyond each side of the' table 63, and the paper extends one inch and a half beyond each sideof the .card board and together they are carried over the table,

- but the side edges of the paper, engaging the folders 68, is turned down and then around the edges of the plates 72, and theniunder the rear end portions of the said plates, the plates preventing the folded portions of the paper from contacting with the glued under edges of the card board. The card board with the paper folded under its side edges, isthen passed in between the cutting rolls 44 and 45, and the folded portions of the paper are pressed against the glued side edges of the cardboard and both board and paper are severed by the knife 48 upon each rotation of the cutting rolls.

When it is desired to produce envelopes inv These rolls are mounted on shafts 85 and86 respectively, whose axial centers are fourteen inches from the centers of the shafts 27 and 28 of the feed rollers.

The shafts 8,5 and 86 are journaled in boxes which are supported in pillow blocks 87 and 88, in the same manner as described in connection with the shafts of the feed rolls and cutting rolls, and the shafts 85 and 87 are provided with meshing gear wheels 89 and 90 respectively. These shafts are also provided with grooved disks 91 and 92, surrounded by the frames 93. The shaft 86 is provided with a sprocket wheel 94, which is connected by a chain 95, with a sprocket wheel 96 on the shaft 28, whereby the said rolls83 and 84 are rotated.

if table 96", similar to the table 66, is supported on a bed plate 97, and extends from the rolls 8384, to therolls 29-89, and on a level with the meeting points of each pair of rolls.

In this arrangement, the card board passes directly to the rolls 2930, but the paper is first passed in between the rolls 8884 and then over the table 96 to the rolls 2930, from which point it travels forward with the card board, but at each rotation of the rolls 8384 the paper is cut in fourteen inch lengths, and the forward end of each strip of paper is engaged by the feed rolls 29-30 simultaneously with the cutting action of the rolls 83-84.

After passing between the rolls 2930, the paper is carried forward and folded and pasted tothe card board in the same man ner as previously described in connection With the full length paper.

The glue pot 62 has secured therein a lonf gitudinal bar 98, to which are secured bifurcate'd metal strips 99, which straddle the glue distributing disks 65 and scrape the glue from the sides thereof, so that onlythe circumferential edges of the said disks are coated with glue, when the disks engage the card board.
